vSPECIFICATION forming part of Letters Patent No. 362,577, dated May 1.0, 1887.

Application filed March 7, 1887.

To all w7t07n, it may concern:

Be it known that we, JAMES E. EMERSON and THMAs M'IDGLEY, citizens of the UnitedA States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have ihvented certain new and useful Improvements inMethods of Manufacturing Wire Belting;

and we do hereby declare the following to be' a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and `use the same.

Theinvention relates to the method of manufacturing wire belting, and has for its object the production of wire belting in which the ends of the transverse wires forming the edges of the belt are secured and protected, and com- 4 paratively a smooth working surface or edge formed on the belt. The article produced is not, however, limited in its use to belts, but

may be .successfully applied to other articles-l such as elevators, mattressess, other metal cloths, armor for defense, fire-proof ,theater-A curtains, bicycle and tricycle driving-straps, straps for buggies and carriages, &c.

Heretofo're it has been proposed to make screwing them into each other, and then to' separate the spirals and pass a rod transversely between them, as in the former construction;

Abut in both of these constructions the ends of the spirals are protected only Aat-their point of overlapping or intersection, and the strain of the belt is upon the transverse rod.

Byour improved construction of wire belt. ing the edges of the belt are entirely covered by metal running at a right angle to the transverse sections, and the ends of the spiral sections secured against displacement, While the strain of the belt is distributed among all of the links of the transverse spiral sections, thus producing a belt of great flexibility and that can be used for any and all purposes to which belts are applied without stretching.

Serial No. 230,025'. (No model.)

The invention will be hereinafter described,

part of this speci'catiomFigure l represents .a single section of coiled wire. Fig. 2 represents two sections beingjoined; Fig. 3, a face view of a portion of a belt before it has been rolled. Fig. 4 lis a reverse view 'of Fig. 3. Fig. 5 represents a face view ofaportion of a belt with a heavier longitudinal coil on the edges. Figli isa reverse view of Fig. 5. Fig. 47 represents anl edge view of Fig. 3. Fig. 8 isa similar view of Fig. 5.v Figs. 9and10 represent the construction shown in Figs. 7 and 8 after rolling. Fig. .11 represents a section showing double coils of wire. Fig. 12 represents a modification in whichthe edges are yprotected and a working-surface formed by headed transverse rods, which pass through the coils. Fig. 13 represents a diagrammatic elevation of the rolls employed for attening thecoils, and Fig. V14 is a section of the metallic rolls.

Reference being had to the drawings and the letters marked thereon, A A represent helical coils of wire, which are woven together why one coil being screwed into theother, as

'shown in Fig.. 2. One coil after another is vadded until a sheet is formed of any desired length. coils and forni a Working-edge for, belting, a coil of wire, B, is screwed into theV ends of the transverse sections A, as shown in Figs. 3 to 7. The coil B engages with two or more of the spirals at each end of the sections, and 'may be' of wire of the same weight and'diameter as the coils A,'as shown in Figs. v3 andl4, or it maybe of heavier wire and larger coils, as shown in Figs. 5 and 6. In the former construction the end coil, when rolled, laps lon one side of the sheet only, as shown in Fig. 9. In the latter construction the coil laps on both sides of the sheet, as shown in Fig. 10, and forms a stronger and more durable edge. stead of screwing the longitudinal coilsinto the ends of the transverse coils, it is obvious that the reverse operation may be resorted to. Instead of the single coils A being used, the coils may be multiplied to form a stronger sheet, as shown in Fig. 11.

The ends of the coils may also be protected To secure and protect the ends of the vIco and kept from spreading laterally by rods a being passed through the coils and headed as at bin Fig. 12.

It will be observed that the links formed by the coils of the adjacent sections intersect and bear directly upon each other without the interposition of rods for connecting the sections.

After t-he sheet has been formed by weaving the coils together, it is pressed between rolls to Hatten the links to prevent them from stretching when put into anyuse in which they are subjected to strain.

ln Figs. 13 and 14 are shown rolls for pressing the sheet, and in which G represents the sheet, D the front or metallic rolls, and E the tension-rolls. The lower roll, F, of the metallic rolls is provided with collars c c, to prevent the coils A from spreading laterally while being rolled, and the upper roll, G, projects into and fills the space between the collars c e of the lower roll. rlhe tension-rolls are made with plain surfaces, which engage with both sides of the sheet (l, and the tension of the sheet is regulated by suitable screws, d, only one of which is shown, and which may beprovided with an interposed spring, c. By preference,thc tension-rolls are made of rubber or other material having an elastic su rface. The object of applying tension to the sheet C while it is being rolled is to keep t-he sections stretched longitudinally, so as to produce a bearing between all of the links in the transverse sections,and to cause the coils to roll out evenly in straight lines across the sheet.

The rolled sheet may be coated with or embedded in rubber, canvas, or other suitable material.

The ends of a sheet maybe connected by screwing a section, A, into them after having opened the ends ot' the links, or it may be connected by lacing or by means ordinarily employed for lacing or securing the ends of belts.

In another application tiled herewith, Serial `No. 230,024, we have claimed the product ot' our method as an article of manul'acture.

Having t-hus fully described our invention, what we claim isd coiled wire to form the length of a belt, and

interweaving the ends of said sections with independent longitudinal sections of coiled wire to form the edges of the belt, and nally rolling the belt to flatten the links, substantially as described.

3. The method of manufacturing wire belting, which consists in interweaving sections of coiled wire to form the length of a belt, and the ends of said sections with independent longitudinal sections of coiled wire, and subsequently passing the whole body between suitable rolls while under longitudinal tension,sub stantially as described.

4. In t-he manufacture of wire belting, the method'of stretching the links of a section and seating them evenly in the links of an adjacent section, with which they engage, which consists in subjecting a sheet of interwoven sections of wire to the action of rolls and keeping the sheet under longitudinal tension while' being operated upon by said rolls, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
